PLASTR-IBOARD-FASTENING MEANS.

\ Application `led May 12, 1926. Seri 1 No. 108,478.

Y Myinvention relates to-new and useful improvements in a plaster board fastening means, and has for its primary object to provide an exceedingly simple and effective 5 method of securing plaster board, hereinafter called sheet material, against furrings, studding, or joists, hereinafter called supports, which may be installed without skilled mechanics.

Another object of the invention is to provide a clip to fasten the sheetmaterial to the supports, which ycan be used in only one way, therefore making it fool proof, and providing a practical, safe construction.

A further object of the invention is to provide -a building construction wherein the wall furrings can be set any distance from the super work and be made strong and durable, as well as providing the proper space for air, which space may also be used /for'the installation of insulating materials `and fixtures, such vas electric wires, gas

pipes, conduits and the like. A

One of the'main advantagesof my invention is that the base for the plaster is of the same or similar material, and therefore is less likely to deteriorate than where metal lath is used as the base for a plaster wall. Another advantage 'of my invention is the reduced cost of constructing solid walls or sub-division partitions between rooms, because it eliminates one application of plaster, or what is known as the scratch coat. In ordinary wall construction the lathing is irst fastened to the supports and the scratch coat applied thereto, this being true where metal lathing is used. After the scratch coat has dried,1 the backing-up coat is applied to ill out the space between the 4 lath and the faces of the supports opposite Pthose on which the lath is secured, after which two applicationsof straightening coats are made, and each of' these covere with afnishing coat, so that six coats of plaster are actually applied, and the first coat in particular must be allowed to'dry for approximately 24 hours before the other;

coats can be put on.

With my invention there is a considerable savin in time, labor and omaterial, because thepaster-board is applied by `the use of myimproved clips instead of lathing which eliminates the use of the scratch coat, so that only five coats of plaster are applied. Theelimination of this one coat of plaster saves material and labor, as well as the time 2which isv required to permit the vdryingclips engage the sheets over a greater area than where nails, tie wires, bolts or screws are used.

With these ends in view, this invention consists in the, details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I

will describe its construction in detail, re-

ferring- Yby numerals to the accompan ing drawings forming' a part of this app ication, in which:

Fig. 1, is a perspective view of a clip'constructed in accordance with my invention` and employed in connection with my method of forming Walls.

Fig. 2, is a perspective view of a section of a plaster board, showing the., manner in which it is fastened by a, clip to a furring bar or support.

Fig. 3, is a perspective view of a slightly modified form'of a clip.

Fig. 4, is a perspective view of a section of laster board illustrating the manner in which the last named clip 1s placed in position.

Fig. 5, is a perspective view 'of the work-- ing face or front of a wall prepared reception of the plaster.

Fig. 6, is a. horizontal sectional. view of for the the intersection of two walls, thereby providing a corner or division of space, illustrating the manner in which m invention will lock the base materials o the walls when it is necessary to start building from another wall of the same material. v

In carrying out my invention as herein embodied, I have shown one form of my clip .in Fig. 1, wherein 10 represents the body which is rather long, and has `a sublos stantial Ll-shaped locking leg ll at one end, and an l.. stay leg l2 at the other end, both legs being so arranged that their terminals are on the same side of their shanlrs.

ln constructing a wall by my method, the line of the wall is designated, and this line then spaced oil at intervals., after which the supports ll, such as studding or furring bars are erected. A sheet of plaster board l5 is then set in place with one edge butting against the starting point or vertical wall. and holes 16 are made in the plaster board adjacent the support in spaced relation equal to the dist-ance between the clip legs, and this may be done with anyT desirable tool, as with a small hand reamer. rl`he locking leg ll of the clip is then entered througl'i one of the holes, and the clip rotated and turned in corkscrew fashion until the locking leg passes behind and engages the support, and near the end of this action, the stay leg will enter another of the holes and grip the sup port on the face opposite that against which the plaster board rests, which will firmly 5' hold the plaster board against the support,

and of course, it is to be understood that any number of these clips may be used according to the dimensions of the plaster board and the number' of supports associated therewith.

After the first plaster board is secured in place another one placed in endwise alignment therewith, and this is continued until the desired number of sheets are erected. The uppermost sheets are then erected with their lower edges resting on the upper edges of others in such manner that the succeeding sets of boards will be in staggered relation to the preceding ones, thus breaking all Vertical joints, as shown in Fig. 5, and, if found desirable, the meeting edges of the several plaster boards both horizontally and vertically may be fastened together by using short pieces of the Supports, as designated In suspended ceiling construction, the holes are first laid out on the sheets of plaster board according to the specifications of spacing, and are then drilled before the sheets are erected.

After the sheets have been. drilled, they are jacked into place by the help of an old man, which latter support the load until the clips can be made fast.

In ceiling work particularly, and on Vertical worlr, if desirable, a small amount of plasterz preferably calcined plaster, (plaster of Paris) is mixed and placed in the hole, through which the stay leg projects, and as this calcined plaster dries very quickly, the clip will be secured against movement 4in a short time.

I have found by actual tests, that where sheet/s of plaster board approximately 4.x 6 feet and 9;@ of an inch or 1/2 inch thick are retrasa used with supports 3/8 of an inch or 1/2 of an inch square with this base core and one and one-half inches of plastering, it is more rigid than a wall of two inches of steel studding, metal lath and plastering. This rigidity is due to the stiffness of the base element or plaster board when held in position by the clips described herein.

lt is to be understood that in a solid wall construction, 4the supports are embedded within the wall, whereas in wall furring, the studding is in the rear or behind the plaster board and iinishcd surface. lVhere double wall furrings are used, the first furring and plaster boards are plastered before the next furl-ing is erected. thus offering a clear space between the two furrings for the circulation of fresh air or heat.

ln walls of greater thickness than those referred to above, the excess amount-of plastering on the support side is taken care of, or securely bound by means of poultry wire 18, or other similar material is placed against the supports and tied at each end. `When this has been done, the plaster boards are erected in the same manner before described, and the clips will hold said poultry wire in place, as well as the plaster boards. This reinforcement of poultry wire will receive the backing up coat of plaster, and will coact with the plaster board, so as to securely hold it and prevent it from becoming loosened which does occur when the weight of the excess plaster is too great for the adhesive qualties thereof.

ln stucco and other wall construction where a. binder for the plaster is desired, the poultry wire may be placed on the outside of the plaster boards as shown at 19, Figs. 2 and 6, and will be held in place by the clips which hold the plaster boards. In actual practice, the plaster boards are temporarily fastened in place by means of a few clips, and the poultry wire is then disposed over the faces of the plaster boards, and all the parts then fastened by substantial clips. When this has been done, the few clips which are covered bythe poultry wire may be removed or cut out by the use of nippers, and then replaced with new clips, which will pass through the poultry wire. This method can also be carried out by the use of single clips, under which conditions, the stay leg is secured to the poultry wire with light gage tying wire, so as to prevent the possibility of dislodgment of the stay leg.

I desire to call attention to the fact that in hollow wall construction, there are two lines of supports with horizontal spacers at intervals to hold the two walls in spaced relation7 and these inside spaces being clear of all foreign materials are adapted for the reception of insulating or whatever other materials may be desired.

In Figs. 3 and t, I have shown a slightly modified form of clip, wherein the body 20 has the U shaped locking leg 21 at one end and an L shaped stay leg 22 at the other end, but these legs project in opposite directions to each other, so that when in use as shown in Fig. 4, the body of the clip really crosses over the supportl instead of paralleL ing the same, and this gives a certain resilient action to the clip to maintain the stay leg against the support.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without de parting from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is:

1. 4A building construction which includes supports, sheets Yof stiff material having tween two adjacent apertures and the legs thereof4 passing through said apertures for coaction with a support.

2. The herein described combination of a support, a sheet of stiff material lying against said support and having apertures therethrough to one side of the support, a clip including a body to span the space between two apertures, a U shaped leg at one end of said body, an L shaped leg at the other 'end of said body, said legs projecting from the same side of the body and passing through'separate ones of said holes for coaction with-the support.

3. The structure set forth in claim 2 in connection with means placed in one of the holes to prevent displacement of one of said legs. l

In testimony whereof, I have hereunto affixed my signature. -f
